Fix pdfi+GS with spot capable devices
This is a chain of problems. Firstly we were unconditionally setting
the 'init_graphics' parameter to pdfi_check_page() which caused it to
close and reopen the device. This throws away the Media Size, CTM and
any cropping/rotation etc which we set up in the PostScript world.
Resolving that then showed that we were not resetting the number of
spots on each page.
Resolving that then showed up a failure to determine that a device was
spot colour capable, because we were doing the pdfi_check_page() call
to retrieve the per-page transparency and spot information when the
PDF graphics state wasn't pointing to the PostScript graphics state,
which meant we were using the nulldevice.
This commit fixes all of the above problems. The various spot-capable
devices now render their content to the correct size/orientation/clip
and get the correct number of spots.
